SMTP Mail Routing Issues

We are having huge issues just now trying to route mail. We have two Gateway Servers which route incoming and outgoing mail via SMTP. We have a global domain document that points a certain domain name out to a specific SMTP server and we have a relay host specified in the Configuration document to send out via the internet.

Routing this way (via the direct connection SMTP connection document) works fine on one of the Gateway Servers but not the other. Whenever we try and force mail through Gateway02 it transfers successfully via the direct connection to the specified IP address, however ,whenever we try and force mail through Gateway01 it routes via the internet, not the direct connection and fails.

It would appear that Gateway01 isn't reading the connection document! We have tried to replace the address book with a known working replica, deleted the connection document and foreign SMTP document.

Can anyone help?

Have you looked at the messaging configuration document for gateway01, under the router/smtp tab--> basics tab. I would compare both messaging configuration documents for gateway01 and gateway02 in regards to how mail routing is occuring. You might find the issue there.

In addition, get the latest R 5 or upgrade to R 6.5 since R5 is no longer supported.

Is the DNS correct for all servers involved ?

I would also rebot the server once you are sure you have good  replica of the address book on it.

I hope this helps !

Check "Routing mail using SMTP" in R5 Administration..

Guessing here.. and having to remember how I did this :)  So, don't shoot me if I'm wrong.   I had two domains, D1: one that had SMTP enabled and  D2 that had to send it's SMTP mail through D1 (a different domain).  What I did, I think, was specify the D1 server as the relay host for internet mail.   D2 had three servers and a hub, so all the SMTP mail went to the HUB which deposited directly  to the D1 SMTP server.


if I have foodomain.com, and I have two servers, foo1, foo2.

I have a Foreign SMTP Domain configured, Domain name: SMTPdomain

Foo1 connection document:
Connection type:      SMTP
Destination server:       anyhost
Destination domain:      SMTPdomain1
SMTP MTA relay host:  ____________ <<< DNS name or IP address of server that has a direct connection to the internet (?)  Or leave blank if this server has a direct connection to the internet and MX records configured for the server.

Foo2 connection document:
Connection type:      SMTP
Destination server:       anyhost
Destination domain:      SMTPdomain1
SMTP MTA relay host:  Foo1<<< If you want foo2 to sent SMTP documents to foo1

-------------
Again, untested, and cobwebs..!

We found the issue! In the Notes.INI on the server the following was set:

IgnoreForeignSMTPDocuments=1

Once this was disabled it worked fine!!!
